Abstract: PROBLEM TO BE SOLVED: To provide a DC-DC converter control device which, even when an inductance value is unknown, can control a switch between on and off stably at high speed.SOLUTION: A DC-DC converter includes a DC voltage conversion unit which converts a DC input voltage to a DC output voltage. The DC voltage conversion unit includes an inductor interposed between an input terminal for DC input voltage and an output terminal for DC output voltage, a capacitor connected to the inductor, and a switch which switches whether or not to apply DC input voltage to the inductor. The DC-DC converter comprises a subtracter which generates a difference voltage signal indicating a difference between a DC output voltage and a reference voltage, a comparator which generates a determination signal indicating a determination result of whether the difference voltage signal is positive or negative, and a delay unit which delays the determination signal by an amount equal to a prescribed delay time. The switch is controlled between on and off based on the determination signal which has been delayed by the delay unit. The prescribed delay time is determined by a DC input voltage, a reference voltage, and a frequency at which the switch is turned on or off.
